What is 5 Stars?
A perfect rating; 5 out of 5. Can pertain to any scale.
Did you see that girl? She gets 5 stars on the hotness scale!
Holy crap you get 5 stars on the crazyass scale!
The number of stars required in Grand Theft Auto: Vice City, to attract what is referred to as "federal love." Federal love entails being pursued by multiple Black SUV's driven by the FBI. A truly magnificent killing spree generally precedes the acquisition of 5 wanted stars.
I thought I could handle all the S.W.A.T. vehicles and cop cars when Bam! I killed yet another police officer and my wanted rating inflated to the dreaded 5 stars. Then I knew a whole new world of hurt.
